From the Wikipedia article

The 1971 aircraft collision at Vienna-Schwechat Airport occurred on 26 December 1971 when, in dense fog at Vienna-Schwechat Airport, a departing Douglas DC-9-32, which was to operate a scheduled flight to Zurich-Kloten Airport, collided with the Beechcraft C55 Baron of a private Swiss owner, whose pilot had accidentally taxied onto the Douglas's runway in the fog. The pilot of the Baron was killed in the accident; the pilots of the DC-9 were able to stop their aircraft before the end of the runway.

Accident sequence

The pilots of the Swissair Douglas DC-9 were carrying out the take-off run from Vienna-Schwechat Airport early in the morning in dense fog when they suddenly and unexpectedly collided with a Beechcraft Baron. The DC-9's right wing struck the Beechcraft's cockpit, killing the pilot. During the subsequent rejected take-off, the DC-9's nose wheel broke and the torn right wing caught fire. The DC-9 came to a stop after around 200 metres with a broken nose landing gear and a burning right wing. The 76 passengers and five crew members on board the Swissair aircraft were uninjured.

Investigation and cause

Cause

The accident investigation found that the Baron had been on the runway without authorisation at the time of the accident.
